<P>PROBLEM TO BE SOLVED: To provide a power converter having a configuration capable of reliably mounting an applied voltage suppressing circuit for preventing damage due to a voltage of a semiconductor switching element, and capable of inspecting its set voltage without damaging IC, or the like, of a peripheral circuit. <P>SOLUTION: In the power converter having the semiconductor switching element 3, the applied voltage suppressing circuit 15 for suppressing an applied voltage of the semiconductor switching element 3 and at least one newly attached component connected so that its absence causes the arrangement of the drive circuit 13 to turn off the semiconductor switching element 3, or a connector 19 equivalent to the component are arranged on a slave substrate 16 (second substrate) having a configuration separated from a master substrate 17 (first substrate) and electrically connected thereto, the master substrate on which the semiconductor switching element 3, the drive circuit 13 and the control circuit 8, or the like, are mounted. <P>COPYRIGHT: (C)2011,JPO&INPIT |
